Because it is a gas, air undergoes adiabatic heating and cooling as it experiences atmospheric pressure changes associated with changing altitudes.

WebThe wind is a moving air that is caused due to the differences in air pressure within our atmosphere. Wind flows from the high air pressure area to the low air pressure area to balance the disparities of air pressure. The more significant the pressure difference, the faster the wind flows. Table of Contents Classification of Winds WebWhen a katabatic wind is warmed by compression during its descent into denser air, it is called a foehn.

WebThe foehn wind occurs when the Chinook wind is forced over a mountain range, causing it to warm and dry. The mountain wave wind occurs when the Chinook wind forms a standing wave pattern over a mountain range, creating alternating areas of wind and calm. Formation: How Do Chinook Winds Form? WebWhen the air that has been heated on the extensive central plateau flows down the escarpment to the coast it undergoes further warming by adiabatic processes. This accounts for the hot and dry properties of these off-shore winds, wherever they occur along South Africa's coastline. [1] [2] WebWindward ( / ˈwɪndwərd, ˈwɪnərd /) and leeward ( / ˈliːwərd, ˈljuːərd /) are terms used to describe direction relative to the wind. Windward is upwind from the point of reference, i.e. towards the direction from which the wind is coming; leeward is downwind from the point of reference, i.e. along the direction towards which the wind is going. sustainability the next challenge
